UNITED STATE SAMUEL EMERSON HARRINGTON, OF NORTH AMHERST, MASSACHUSETTS.

SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 407,952, dated July 30, 1889.

Application filed May 1, 1889. Serial No. 309,208. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL EMERSON HAR- RINGTON, a citizen of the United States, residing at North Amherst, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Sash-Holders and Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improvement in sashholders, and in combination with the improvement ot a locking device; and it has for its object to provide a holder for the upper and lower sashes of a window, which is operated from the insideof a room to hold said sashes open, the one lowered and the other raised to any relative positions, or to hold either sash open while the other is closed, or to hold both closed and locked.

The device is so constructed and arranged as that by a single movement of a crank-lever in the hands of the operator the upper and lowersashes may be moved toward each other horizontally and pressed against the partingbead of a window-frame, and so held at any desired points in the vertical traverse of 'the sashes.

In the drawings illustrating my invention, and which form a part of this specification, Figure 1 is a vertical section of a window, one side of which is broken away to exhibit in elevation the holding and locking devices as secured in one of the hanging-stiles. Fig. 2 is a horizontal section of the window and the supporting and locking devices for the same. Fig. 3 is an edge elevation of the sash-holder.

Similar reference-letters indicate like parts in all of the figures.

Referring to the drawings, A A is the bedplate of the holding device, formed in two parts, and thusrendered adjustable to suit any thickness of window-sashes, made, preferably, of metal, and secured firmly in the hangingstile of a window-frame by screws which pass through said plates.

One portion of bed-plate A Aas, for instance A-n1ay be permanently fixed to the hanging-stile of the window; but the portion A being provided with long slots Z Z and that of A with screws m, the heads of said screws hold the two parts of said bed-plate adjustably together when the said plates are in proper position.

B is a clamp linked to an arm C, provided with a slot 1) and holes e. A screw b passes through the slot Z) and enters the portion A of bcd-plateA A. The clamp B is provided with a clamping-jaw (Z, having an inwardlybent lip adapted to bite upon the sash laterally.

13 is a clamping-arm provided with a slot f and having a clamping-j aw d formed like the clamping-j aw previously described. The portion A of bed-plate A A has a perforated boss g projecting through the slot f of the clampingarm l3, and this, in connection with apin h, which passes through said boss on top of j, provided with a screw-threaded opening.

Pivoted to a projecting part of the bed-plate A is a square sleeve E, to which are secured at opposite ends crank-arms F G, the former of which is permanently fixed to said sleeve, and the latter of which is provided with a thumb-knob and arm, which may be removed, if necessary.

H is an arm, screw-threaded on one end to enter nut j, and perforated on the opposite end to fit over a pin projecting from the crankarm F. The screw-threaded portion of the arm H engages the screw-threaded opening of the swivel-nutj, pivoted to the pivoted leverarm D.

The arms of clamps B B are respectively influenced somewhat by springs 7c secured to the bed-plate, which bear against the edges of the said clamps and keep their jaws normal to the sash against which they may bear.

In connection with the sash-holding device I have arranged alocking device, the same to be employed when it is desirable to raise the lower sash a short distance and lower the upper one a corresponding distance for ventilating purposes. If this were done to the windows of the first story of a house, especially without a locking device, thieves might reach in and release the clamped sash byopcrating the crank Gg'but in using the lock with the holding device, the sash could not be released without the proper key.

It will be remembered that the sleeve E was previously mentioned as being square in transverse section. This sleeve I use in connection with a slotted tumbler and key to form the chief features of the locking device. The bed-plate A being extended upward, it serves as a bearing for the tumbler M of the lock. Said tumbler M is pivoted to the bedplate at m, and its ends, which are of slotted form, are within reach of a suitable key and the sleeve F.

0 is the key-hole, and 19 represents the key. The lock is provided with a suitable casing, which incloses the tumbler -M. When the key 1) is turned to the left, it engages one wall of U-shaped slot P on the key side, and, controlled by the pivot at m, the slot '1" will clasp the square portion of the sleeve E and hold the said sleeve so that the cranks F and G cannot be moved. The key 19 being now removed, the sashes cannot be released except by the person holding the key.

In using the holding device, either or both of the sashes are opened, and the crank G in the hand of the operator is revolved a quarter of a revolution. Cranks G and F being in radial line, the arm H moves the swivel-lever arm 'D about its pivot t', and at the same time the clamping-bars B B are moved toward each other and their jaws embed themselves in the respective sashes. At the limit of movement of the arm D to effect the holding of the sashes both cranks F and G are in line with the screw-threaded arm H, so that the jaws of the clamps B B cannot be released except by a reverse movement of the crank G.

Having thus described my invention, what 2. The combination, with the bed-plate A -as a bearing,.the pivoted lever D, the arm 0 and clamp B, united by a compensating link, the clamp B, and pivots 'i 'i, and the windowsashes, of the swivel-nut j, pivoted to said pivoted lever D, the crank F and G, and the screw-threaded arm H, as and for the purpose set forth.

The combination, with the holding device for the sashes and the square collar F, as described, of the locking device composed of the pivoted tumbler-plate, having slots at opposite ends, and the key to operate said tumbler, substantially as and for thepurpose set forth.

4. The combination, with the double holding and locking device composed of clamps B d B (1, arm 0, linked to said clamp B d and lever D, of the bed-plate composed of parts A A, adjustably arranged with reference to each other and the window hangingstile by slots and'holding-screws, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
